As electrons flow through complexes in the inner mitochondrial membrane,protons are moved from the matrix to the intermembrane space.This can make the pH
A)the same in the matrix and the inner membrane space.
B)lower in the matrix.
C)lower in both the matrix and the inner mitochondrial space.
D)lower in the inner membrane space.

As protons are moved from the matrix to the intermembrane space, the concentration of protons increases in the intermembrane space, making it more acidic (lower pH). Therefore, the correct choice is D. The matrix will have a higher pH as it loses protons.
